LAMP-SUPPORT.

Specification of Letters Patent.

Patented Apr. 2a, 1917.

Application filed March 23, 1916. Serial No. 86,215.

To all wiwm it may concern:

Be it known that 1, Aaron 0.. SWAIN, a citizen of the United States, residing at La J olla, in the county of San Diego and State of California, have invented certain new and useful Improvements in Lamp-Supports; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in attachments for sewing machines and more particularly to lamp supports used in connection therewith.

The principal object of my invention is to provide a very simply constructed lamp support which can be readily attached to or detached from a sewing machine top, table, desk or similar article.

An additional object is to provide a device which can be very chea ly manufactured yet which will be very e cient in use.

With the foregoing and many other objects in view, my invention resides in certain novel features of construction, combination and arrangement of parts which will hereinafter be more particularly described.

In the accompanying drawing-:

Figure 1 is a perspective view of the upper portion of a sewing machine viewed from the rear and showing my improved support applied thereto;

Fig. 2 is a central vertical longitudinal sectiog onthe plane of the line 2-2 of Fig. 3; an

Fi 3 is a vertical transverse section on the p ane of the line 3-3 of Fig. 2.

The preferred embodiment of my invention is disclosed in the several figures of the drawing and in Fig. 1 is shown attached to the top '1 of a portion of a sewing machine M on the rear edge thereof preferably directly behind the arm of the machine.

The support comprises a shelf or platform.

1 of any preferred material and constructed in any suitable size upon which a lamp may be placed, said platform being provided with a flange 2 around its rear and side edges to prevent the lamp from being jarred off: the shelf by the vibration of the machine.

A bracket having an attaching foot 3 is secured to the bottom of the platform 1 and has an arm 4 extending downwardly thereform 1 are extended forwardly beyond the inner edge thereof to form the arms 10 which are adapted to overlie the machine to as shown. These arms 10 cooperate wlth the head of the clamping screw 7 to secure the support to the machine top or table, said top being gripped therebetween.

When the support is to be used primarily with sewing machines the inner or front edge of the platform 1 is beveled downwardly as shown at 11 and is adapted to cooperate with the usual inclined edge 12 of the top '1, thus making a very neat appearance. From Fig. 2 it will be seen that the top of the shelf 1 is flush with the upper surface of the machine top T, thus allowing the lamp to be partly supported by the shelf 1 and the top T, or wholly by the platform' 1. Furthermore, by extending the flanges 2 to form the arms 10, means are provided not only for cooperating with the clamping screw, but also for preventing the lamp from sliding from the machine top when it is drawn close to the arm of the machine and only partly supported by the shelf 1. In other words, the arms 10 extend far enough across the machine top to prevent the lamp from being moved by vibration therefrom and upset when only partially supported by the shelf. It is obvious that this simply constructed lamp support will fill a long felt want of those persons who find it necessary to use a sewing machine at night, since with a machine of ordinary construction it is practically impossible to obtain sufiicient light at the back of the machine where it is designed to place I this device.

Various changes may be made in the form and proportions of the article without departing from or sacrificing any of the principles of the invention, for instance when the support is 'to be used on a ble or machine top having straight edges, the edge screw carried by said jaw, whereby the table will be clamped between said arms and the jaw.

In testimony whereof I have herennto set 15 my hand in presence of two subscrlblng witnesses.

Amen c SWAIN. Witnesses A J. B. Pm, E. R. BASKEWHLE.
